My brothers and sisters in Christ, just because something you want to say is right and biblically backed, doesn’t mean you need to say it. In other words, just because you know the right things to say, doesn’t mean you have love in your heart for that person or group to say it. That, unfortunately is what’s called “self righteous”. Be mindful of the Holy Spirit. Only say stuff ESPECIALLY in correction, if you can say it with that person or groups salvation in mind.
